Aug. 31, 1965 R. CHUPICK HEADLINING LISTING WIRE SUPPORT Filed Sept. 24, 1962 zdf TTORNEY United States Patent 3,2Il3fi3tl HEADLINEJG LiS'IihlG WERE SUEPUIRT Ronald Chupick, Livonia, Mich, assignor to General Motors Corporation, Detroit, Mich, a corporation of Delaware Filed Sept. 24, E62, Ser. No. 225,486 '7 Claims. (Cl. Mai-137 This invention relates to vehicle bodies and more particularly to a headlining listing wire support for vehicle bodies.

it is well-known to provide vehicle bodies with listing wires or rods which extend transversely of the passenger compartment and support the body headlining fabric or material. Normally the listing wires are supported only at their ends in the side roof rail structure of the body, but in certain instances, due to the long span of the wire or otherwise it is necessary to support the wire intermediate the attached ends thereof.

This invention provides a support which cooperates with the listing wire in supporting the headlining so that the headlining does not sag and an exceedingly rigid listing wire is not required.

One feature of this invention is that it provides a headlining listing wire support which is fulcrumed on the body and includes an end portion adapted to support the listing wire.

Another feature of this invention is that it provides a headlining listing wire support fulcrumed intermediate the ends thereof on the body, with one end portion thereof being biased in a downward direction to bias the other end portion thereof, which supports the listing wire, in an upward direction.

A further feature of this invention is that it provides a headlining listing wire support which includes a resilient lever member fulcrumed intermediate its ends on the body, with one end portion thereof bearing against the body roof structure so as to be biased in a downward direction and causing the other end portion of the lever to be biased in an upward direction about the fulcrum and thereby support a listing wire against downward displacement.

These and other features of the invnetion will be more readily apparent from the following specification and drawings wherein:

FIGURE 1 is a partially broken away partial side elevational view of a vehicle body embodying a headlining listing wire supported according to this invention;

FIGURE 2 is an enlarged perspective View of a portion of FIGURE 1;

FEGURE 3 is an enlarged plan view of the support;

FIGUR 4 is an elevational view of the support;

FIGURE 5 is a view similar to FIGURE 1 showing a second embodimen of the invention;

FIGURE 6 is a view taken generally along the plane indicated by t6 of FIGURE 5; and,

FIGUhE 7 is a view taken generally along the plane indicat d by line 7-7 of FIGURE 5.

Referring now particularly to FIGURE 1 of the drav ings, a vehicle body designated generally as It} includes a roof structure 12 which includes a roof panel 14 and a transverse roof rail or reinforcement member 16 having its rearward flanged edge secured to the flanged edge of roof panel 14 to define the opening for the rear window 17 of the body. Member to includes a generally vertically disposed portion 13 provided with an elongated slot or aperture 153 which is located approximately at the longitudinal center line of body It Panel 14- is concealed by headlining 2% having the front, rear and side edge portions thereof attached in a conventional manner to the body to form an attractive false ceiling for the ice passenger compartment. Semi-rigid headlining listing rods or wires 22 extend transversely of the body intermediate the roof panel 14 and the headlining 20 at spaced intervals along the length of the roof structure and provide a support for the headlining to prevent sagging of the headlining intermediate the edge portions thereof. The ends of wires 22 are secured in a conventional manner to the side roof rail structures of the body, and the wires are self-supporting between their secured ends. Loops 24 stitched to the headlining fabric support the fabric on the listing wires.

Referring now to FIGURES 2,. 3, and 4, the listing wire support of this invention generally comprises a lever-like member 3% fulcrumed intermediate the ends thereof on the lower edge of the slot 19. Member 30 is formed from a single piece of spring wire or rod which is bent to the desired shape and has the end portions thereof twisted at 32 to form a closed loop structure having a generally V shaped portion 3 and a generally U shaped portion as, the legs of which are interconnected by holding and fulcrum bends 38. The end portion 40 of member 30 is joined to the twisted portion 32 by an offset portion which cooperates therewith in providing a listing rod nesting bend 42. End portion 49 is sharpened at its free end and the base 4-4 of U shaped portion 36 is rubber sleeved.

Support 3% is mounted on the body by moving portion 36 through the slot 19 until bends 38 rest on the lower edge of slot 19 to fulcrum member 3-9 on member 16. After support 3i) is initially fulcrumed on member 16, the V shaped portion 34 is manually grasped and pulled downwardly to move base 44- of portion 36 upwardly into engagement with root panel 14. Portion 34 is then moved further downwardly about the bends 38 until it is located in the position shown in FIGURE 1, and the sharpened end of portion 41 is then caused to pierce loop 24 immediately under listing wire 22 to nest the listing wire in bend 42. As shown in FIGURE 4, the portions 34 and 36 are normally located at a predetermined angle of approximately degrees, and this angular relationship is increased when portion 34 is located in the position as shown in FIGURE 1. The internal stress developed in member 3a) by deforming it into the position shown in FIGURE 1 acts to return portion 34 to its normal angular relationship with portion 36 and thus causes end portion lli to resiliently support the listing wire 22 and the headlining 2th against downward displacement relative to the roof panel 14.

The second embodiment of this invention is intended for use with vehicle bodies which include the usual roof panel and a generally box-like roof rail structure. This embodiment diifers from the first embodiment described above primarily in the manner of engagement of the lever member with the roof structure and allows for economies in the fabrication of the lever member.

Referring now to FIGURE 5, wherein like numerals indicate like parts, the roof structure 12 of the body it) includes the roof panel 14, the roof rail 16, and an additional reinforcing member or roof rail 46 having its for ward flanged edge welded to the forward flanged edge of rail 16 and its rearward flanged edge welded to the rearward flanged edges of rail 16 and roof panel 14. Rails 16 and d6 thus provide a rigid box-like rail structure reinforcing body Ill. A generally horizontal downwardly sloping portion of rail as is provided with an elongated slot 5%.

The listing wire support of this embodiment of the invention generally comprises a lever like member 52 formed from a single strand of spring wire or rod which is bent intermediate its ends into an obtuse angle to provide a support portion 54, a holding and fulcrum bend 56, and a retaining head portion 58 having angularly disposed legs so and 62. Leg 62 is located normal to portion 54 S and includes a lateral semi-circular seating bend 64 which is adapted to be received in slot 50 when member F2 is mounted on rails 16 and 46. A sharpened end portion 7% of me .1 or 52 cooperates with portion 54 in providing a listing wire seating bend 72.

Member 53 is mounted on the body by moving portion 58 through aperture 19 into engagement with the downwardly sloping portion of rail 46, and then forcing the portion 53 rearwardly along the rail 4-6 until bend es rests on the lower edge of aperture 19, whereupon bend 64 is positioned within slot 59 to secure member 52 against lateral movement. Portions 54 and 58 are normally located at a predetermined angle of. approximately 150 degrees and this angular relationship is increased when member 52. is mounted on the body as portion 54 resiliently engages a deadener panel '76 secured to the roof panel 14. The sharpened end portion 74 pierces loop 24 immediately under listing wire 22 to seat the listing wire in bend 72 and resiliently support the listing wire and headlining 2 Certain modifications may be made to this embodiment of the invention, such as dispensing with bend 64 and slot 53 and providing downwardly extending eads on the rail 4s to engage legs 6'9 and 62 to prevent lateral displacement of the retaining portion 58, and providing a lanced tab in rail 46 to receive either leg 60 or leg 62 to prevent vertical displacement of portion 58.

Thus this invention provides an improved listing wire support for vehicle bodies.
